Abstract
The invention relates to a manufacturing method of a spiral spring and a variable-pitch spiral spring, and the manufacturing method of the spiral spring at least comprises the following steps: S1, stacking at least two continuous fiber prepreg sheets according to + 45 degrees and-45 degrees, and cutting the continuous fiber prepreg sheets into a preset size to obtain a roll material; s3, inserting an iron wire into the hollow pipe to manufacture a reel; s5, the reel is placed on the roll material by 180 degrees, pipe rolling is carried out, and after pipe rolling is completed, the iron wire is pulled out of the hollow pipe to obtain a preformed body; s7, the preformed body disc is attached to the inner mold, and the outer mold covers the preformed body disc; and S9, after the preformed body is cured, demolding is conducted, and a finished product is taken out.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a manufacturing method of a coil spring and a variable-pitch coil spring. Background technique [0002] As one of the most widely used components in modern automobile suspension systems, coil springs not only serve as load-bearing parts to carry most of the vehicle's weight, but also serve as buffers to reduce the discomfort of passengers traveling caused by road bumps. The advantages of the coil spring are that the structure is relatively compact, the space occupied is small, the manufacture is relatively simple, the customizability is strong, and the energy absorption rate is high. [0003] At present, the coil springs used in passenger cars are mainly made of metal structure. Although the metal coil springs can meet the elastic performance and mechanical performance requirements of the vehicle coil springs, the metal coil springs also have certain defects, such as heavy...
